Subject: [PATCH] apparmor: Fix an error code in verify_table_headers()
Date: Mon, 19 Mar 2018 09:12:31 +0000	[thread overview]
Message-ID: <20180319091231.GA7409@mwanda> (raw)

We accidentally return a positive EPROTO instead of a negative -EPROTO.
Since 71 is not an error pointer, that means it eventually results in an
Oops in the caller.

Fixes: d901d6a298dc ("apparmor: dfa split verification of table headers")
